Settings > Wi-Fi Settings > Basic Settings
Set Wi-Fi Switch to Enable or Disable to control the availability of your MobiiConnect 4G Wi-Fi. If disabled, other
devices will not be able to connect to the MobiiConnect 4G wirelessly.
On this page you can customise your Network Name (SSID) and Password (Pass Phrase) if desired.
Password Security Mode should be set to WPA-PSK/WPA2-PSK for optimum security.
Setting Broadcast Network Name (SSID) to Disable will hide your network name from all Wi-Fi devices.
You’ll need to manually enter your Network Name and Password on a device to connect to the Wi-Fi.
Click Apply to save any changes.
If you change your settings, all devices connected to the Wi-Fi will need to re-connect using the new settings.
